  • Patent number: 8148465
    Abstract: The invention relates to a process for free-radically initiated heterophase polymerization, in which the polymerization of ethylenically monomers proceeds in a phase dispersed in the continuous phase, characterized in that one or more additives which are soluble in the continuous phase and insoluble in the disperse phase and stop the polymerization of the ethylenically unsaturated monomers in the continuous phase is/are added before or during the polymerization.

  • Publication number: 20120071619
    Abstract: In the production of isobutylene-based elastomers the product obtained from the polymerization process is often in the form of a stream. Described herein are an apparatus and a process for removal of hydrocarbon liquids from the elastomer. The process comprises the steps of obtaining a stream comprising hydrocarbon liquids, either solvents or diluents, and an isobutylene-based elastomer; passing the stream through a kneader to volatize the hydrocarbon liquids from the elastomer.

  • Patent number: 8133835
    Abstract: Provided are a molecular weight controllable, high 1,4-trans polybutadiene catalyst system, and more particularly, a four-component catalyst for preparing 1,4-trans polybutadiene with high yield, the catalyst comprising a cobalt compound, an organoaluminum compound, a phenol-based compound, and a phosphorus-based compound used to prepare 1,4-trans polybutadiene by polymerizing butadiene or a butadiene derivative, and capable of controlling the molecular weight of 1,4-trans polybutadiene by regulating the amount of the phosphorus-based compound. In particular, 1,4-trans polybutadiene may be efficiently applied to tires, belts, or the like since it has excellent tensile strength, tear strength, and cut & chip properties with increasing processability.
